PKAA, Dream Canyon Project

The State of Colorado Department of Natural Resources, Division of Reclamation, Mining and Safety, is soliciting documented quotations for the Dream Canyon Project, a mine closure initiative located in the Sugarloaf District of Boulder County, Colorado. This project involves comprehensive safeguarding of hazardous mine features through various closure methodologies applied to privately owned properties, including machine backfill operations, installation of corrugated steel pipe, rock bulkhead placement, grating systems with bat cupolas, rock fill placement, shaft footers, and site revegetation. The bid schedule encompasses nine line items covering mobilization and demobilization (1 job), project safety and environmental planning (1 job), sediment control (300 linear feet), mine closure installations across 20 identified features (including shafts, stopes, and adits), and optional work items such as imported rockfill, imported fill materials, grating, shaft footers, equipment rental, and road base improvements. Contractors must provide comprehensive project safety, health, and environmental action plans addressing fall protection systems, White-Nose Syndrome decontamination protocols for bat-affected sites, OSHA compliance, noxious weed mitigation, and stormwater sediment control measures. A mandatory pre-bid meeting and site inspection was held on April 16, 2026, at 10:00 a.m. MT at the Dream Canyon Hiking Trail Parking area; written inquiries were due by 4:00 p.m. MT on April 20, 2026, with electronic bid submissions required via Colorado Vendor Self Service by 4:00 p.m. MT on May 5, 2026, and bid opening scheduled for May 6, 2026. The project construction period spans June 3, 2026, through August 1, 2026, with a completion timeline of sixty calendar days following the Notice to Proceed, including ten calendar days for mobilization. Bidders must submit a List of Equipment Offered form detailing all equipment to be used and acknowledge receipt of all addenda, including Amendment No. 1 (issued April 17, 2026) and Amendment No. 2 (issued April 24, 2026), with the revised bid schedule reflecting modifications to eight feature specifications and deletion of one feature from the original scope.
